Overview

We provided structural design services for New York's Roosevelt Island Tram when it opened in 1976 as the first aerial commuter tramway in North America. The tramway runs every 7-15 minutes and can carry 125 people up to 250 feet above the East River.

In 2010, we provided structural renewal services for the tramway's $23 million rehabilitation and equipment upgrade. 

Highlights

  • We used SAP computer models to perform our analysis and worked within a tight design and construction schedule to accommodate heavier loads created by new tramway cables, cars and machinery
  • We also designed tower and station reinforcements as well as completely new steel head frames for each of the three towers.
  • Our work also took into consideration new wind, earthquake, ice and snow codes that affect the highly active tramway, whose two cabin cars make more than 115 trips per day.
  • The tram follows the north side route of the Queensboro bridge. We've provided bridge inspection and rehabilitation services for the bridge’s 2014 and 2016-2017 biennial inspections as well as design and construction support for the subsequent reconstruction of the bridge’s upper deck system.
